Davies’ colletes – (Colletes daviesanus) was busy foraging on the oxeye daisies
in my garden last summer. They typically
appear in spring, and can be seen through to September in the UK.
Davies’ colletes gather pollen from a range of composite flowers - such as these oxeye daisies in my garden, and wildflowers typically seen on flowery verges and wild brownfield sites, such as ragworts, yarrow, tansy, common fleabane, mayweeds and chamomiles.
However, they will forage for nectar from a wider range of flowers, including garden flowers, to gather nectar.
Females range from around 6.5 - 7mm with males slightly smaller from about 5.5 - 6.5mm - actually making them slightly smaller than the Western honey bee.
I have repeatedly seen on social media the mention that if a bee has much hair (a tuft or 'moustache') on the front of its face, it is a male. However, this is not always the case, and can be misleading. The female of this species clearly has quite a lot of tufty hair on its face!
Davies' colletes may nest in large groups in dry soils and south facing slopes, or may nest in walls in soft mortar or sandstone.
When creating nest cells, these bees secrete a cellophane like substance from the abdomen with which they line and glue their nest cells. This substance is not only waterproof, it protects the nest cells and its contents from harmful fungi.
